Social distancing guidelines to limit the spread of the SARS-CoV-2 virus vary considerably, and the effect of mask type on these guidelines has yet to be studied. We report high-fidelity numerical simulations of human coughing to study the transport of various sizes of saliva droplets with and without facial masks. Our results show that, in indoor environments, wearing a mask coupled with existing CDC social distancing guidelines effectively protect others from getting exposed to pathogen-carrying saliva particulates.
